La vulnerabilidad permit\u00eda eludir el sistema de autenticaci\u00f3n y conectarse a la API de gesti\u00f3n de lanzamientos con derechos de administrador mediante el env\u00edo de una solicitud con cualquier clave e indicando uno de los administradores en el campo del nombre de usuario. <\/p>\n<p>Los derechos obtenidos en caso de explotaci\u00f3n exitosa de la vulnerabilidad otorgaban al atacante la posibilidad de modificar los enlaces de los lanzamientos de Python y los metadatos para verificar la correcci\u00f3n de los archivos subidos, alojados en la p\u00e1gina python.org\/downloads. Sin embargo, la vulnerabilidad no permit\u00eda modificar el contenido de los archivos existentes con los lanzamientos. <\/p>\n<p>La auditor\u00eda de la base de datos y los registros no revel\u00f3 signos de explotaci\u00f3n de la vulnerabilidad. Tambi\u00e9n se supone que la sustituci\u00f3n de los enlaces a los lanzamientos no pudo pasar desapercibida, ya que muchos proveedores durante la carga utilizan adicionalmente un sistema de verificaci\u00f3n criptogr\u00e1fica de c\u00f3digo Sigstore y comprobaci\u00f3n utilizando claves PGP.<\/p>\n<p>La vulnerabilidad estuvo presente en el c\u00f3digo desde 2014 y fue causada por la mezcla en un solo c\u00f3digo de los controladores para accesos como invitados y la autenticaci\u00f3n por claves para la API. En caso de fallo de la autenticaci\u00f3n por clave para acceder a la API, el c\u00f3digo realizaba un retroceso para utilizar el acceso de invitado. <\/p>\n<p>La vulnerabilidad fue identificada el 23 de febrero y corregida al d\u00eda siguiente, tras lo cual se realizaron varias verificaciones de integridad de la infraestructura: el 25 de febrero se analizaron los registros y las copias de seguridad de la base de datos, todos los recursos disponibles para descarga fueron verificados utilizando firmas digitales del registro de Sigstore y claves PGP, y se llev\u00f3 a cabo una auditor\u00eda de la base de c\u00f3digo de los servicios utilizados. El 23 de abril, la base de c\u00f3digo fue revisada adicionalmente con herramientas de IA, y el 1 de junio, se contrat\u00f3 a la empresa Trail of Bits para una auditor\u00eda externa de la infraestructura python.org y los procesos de generaci\u00f3n de lanzamientos de Python.<br \/>\n<br \/>Fuente: <a content=\"nofollow\" rel=\"nofollow\"
